MACHNE FOR RAISING' AND THROWING RAILWAY-TRACKS.

Application filed January 18, 1917.

' zens of the United States, residing at Buhl,

in the county. of St. Louis and 'State of Minnesota, have invented new and useful improvements in Machines for Raising and Throwing Railway-Tracks,of which the following is a specification.

Present methods of moving railway tracks require large gangs of laborers, who with bars, jacks and other hand tools lift and shift the track as desired. This work is slow and expensive and the increasing scarcity of laborers renders track shifting a perplexing problem in railway and mining projects. The demand for quick track readjustment on the main lines of railways'and in open pit mines, where the banks are rapidly broken away, suggests the necessity for mechanical means for securing the desired result.

The object of our invention is to provide a ,device of this character which is simple, durable, etlicient and economical in operation.

More specifically, it is our object to provide a self-propelled car adapted to rest upon the track to beshifted, said car being supplied with clamps for rigidly securing the same to the rails and with a jack arranged to lift and shift said car and rails sidewise.

A further object is to provide in a device of this kind `ellicient and easily operated mechanism to firmly clamp the car to the1 rails and to release-said car from the rai s.

`Another object is to provide in a device of this character apower driven jack having a thrust boom rpivoted to swing transversely with respect to the car and adjustable from one side thereof to the other, where by the car may be lifted and thrown sidewise in either direction.

1n the drawings, Figure 1 is a side elevation of our improved device; Fig. 2 is a plan View thereof; Fig. 3 is an end elevation of the same; Fig. l is a sectional View taken on the line vll of Fig. 1; Fig. 5 is a detail sectional view taken on the line 5-5 'of Fig. Fig. 6 is a detail sectional view taken on the line 6--6 of Fig. 5; and Figs. 7 'and 8 are detail views in elevation showing thebase of thc thrust boom and illustrating the bracing rods 'for rigidly se- Specication of Letters Patent.

curing the boom in upright position upon its pedestal..

Our improved machine comprises broadly, a car, clamps t0 rigidly secure the car to the rails uponwhich said car rests, a jack adjustable on the car and supplied with a pivoted thrust boom adapted to bear upon the bed of the track and raise the car with the rails,l so as to shift said car and rails sidewise in either direction.

Referring to the drawings, we have used the reference numeral 10 to indicate the frame of the car which may be constructed of steel beams or other suitable structural material. This frame is mounted upon a drivlng axle 11 and a floating axle 12; both axles being supplied with flanged wheels 13. The connection between the frame 10 and driving axle 11 consists of bearings la which are secured upon the frame and revolubly re-.

ceive said axle. The floating aXle 12 is revolubly mountedlin bearings l5 on a yoke 16; said yoke being pivoted beneath a transverse beam 10*1 on thc frame 10 by means of a king pin 10h. Torsion rods 17, secured to the yoke 16 and frame 10, prevent the horizontal displacement of the aXle 12 and allow vertical tilting movements thereof with respect to the frame. This floating mounting for said axle compensates for irregularities in a track and permits normal contacts of all of the wheels with the rails, without distorting the frame of the car.

The mechanism for rigidly securing the car to the rails of a track comprises four identical-clamps A; one clamp being arranged near each wheel. Said clamps are simultaneously operated by means of levers 18 and 19 near the operators platform 2O at one end of the car. Each clamp is formed with two arms 21 and 22.l The arm 21 has a hook 23 adapted to engage the rail beneath the head thereof and the arm 22 is formed with a catch 2a adapted to abut against the end of a coperating latch lever 25, as will be' hereinafter described. A bearing 26 at the junction of said arms 21 and 22 is journaled upon a crank 27 of a crankshaft. 28. `We supply two of these crank shafts 28 which eXte'nd longitudinally beneath the side beams of the car frame and are journaled in bearings 29 upon said frame. The ends of each crankshaft are bent to form the cranks 27 upon which said clamps A are journaled.. Actuating arms 30, secured to sa1d crankshafts 28, pass inward and overlap each other at their ends. Said ends have slotted pivotal connections with a link 31 which 1s attached to a crank arm 32 on a shaft 33 upon which is mounted the hand lever 18. This lever 18 is supplied with a hand latch 34 and a notched segment 35 therefor, so that said lever may be set in various positions, as hereinaftervindicated. The latch levers 25, above mentioned, are secured in pairs on shafts 36, revoluble in bearings 37 on the car frame. Each lever 25 is slotted longitudinally and slidably receives a link 38 which is attached to the arm 22 of one of the clamps A. These levers 25 are raised and lowered by the oscillation of the shafts 36 and by reason of the link connections with the arms 22 of the clamps A cause the latter to be turned, whereby the vhooks 23 on the arms 21 of said clamps may be shifted to operative positions against the webs of the rails (solid lines, Fig. 6), or removed therefrom (dotted lines, Fig. 6). The levers 25 are so proportioned that the ends thereof engage the catches 24 on the clamps when the hooks 23 on said clamps lie beneath the heads of the rails. The shafts 3 6 upon lwhich said levers 25 are mounted are connected through arms 39 and rods 40 with the hand lever 19 at the end of the frame; said, lever being supplied with a hand latch 41 and coperating notched segment 42 to secure the lever in various positions. In clamping our car to the rails of a track, the hand lever 19 is manipulated to swing the clamps A into position with the'hooks 23 against the webs of the rails. The hand lever 18 is then shifted to turn the crankshafts 28 and raise the cranks 27 upon which said clamps are mounted, thereby drawing the hooks 23 'snugly against the lower sides of the rail heads. It will be noted in this connection that the latch levers 25 secure the catches 24 on the end of the arms 22 when the crankshafts 28 are turned to raise the hooks 23 and that the cranks 27 arearranged on said crankshafts 28 so that they rest on dead center when the hooks 23 are drawn against the rails, thereby relieving the` lever 18 and eon nections 'thereto from strains. To release the car from the rails, the lever 18 is first reversed to low er the hooks 23 and the lever 19 is then reversed to swing the clamps and carryl the hooks'23 away from the rails to safe positions above the ties of the track.

The jack on the car comprises at transverse'lyadjusta'ble carriage B, an oscillatory thrust boom 43 mounted on said carriage, power operated mechanism for shifting the boom longitudinally and hand operated mechanism for tilting said thrust boom and adjusting said carriage. The carriage includes a bed 44 which is slidable upon the frame inretainin'g guides 45. This bed is supplied with a pair of standards 46 and 47 and is formed with a longitudinal opening bly mounted in the bearing 48 to receive the thrust boom 43. A. shaft 49 is revolubly mounted in said standards, and upon said shaft is a loosely pivoted sleeve 50, in which the boom 43 is slidably mounted, a fixed spur gear 51 in mesh with a rack on said boom, a lixed worm wheel 53 and a loosely mounted bevel gear 54. The worm wheel 53 meshes with a worin gear 55 feathered on a shaft 56 in bearing supports 57 upon the car frame. Said worm gear is secured between bearings 58 on the standard 47 of the carriage and is thereby held in mesh with the worm wheel when the carriage is shifted. This shaft 56 is connected with the power shaft 59 of an engine 6() by means of a sprocket chain 61, which passes over a sprocket wheel 62 on said shaft and over a sprocket wheel 63 on a driven clutch member 64 on said power shaft. A driving clutch member 65, actuated by a hand lever 66, co-acts with said driven clutch member 64 and connects the engine with the thrust boom 43 through the power transmitting mechanism described. The power shaft 59 is supplied with an ordinary clutch and reverse gear mechanism (not shown); the former being actuated by means of a suitable hand lever 67 and the latter by a hand lever 68. Thus it will be seen that the thrust boom 43 may be moved by power longitudinally in either direction and at variable speeds with respect to the speed of the enme.l

A strap 69, arched over the worm wheel 53, rigidly connects the sleeve 50 with the loosely mounted bevel gear 54 on the shaft 49. This gear coperaties with a bevel gear 70, feathered on a shaft 71, which is revolusupports 57. This bevel gear 70 is secured in mesh with the bevel gear 54 by means of an arm 72, which is revolubly secured to said gear at one end and rigidly secured at its other end to the standard 47 of the carriage. A han dle 73 on one end of the shaft 7l is furnished tooscillate said shaft and swing the thrust boom 43, whereby the desired angular position of said boom is obtained.

The mechanism for adjusting the carriage B transversely on the car frame and securing the same in the various positions thereon comprises a threaded .shaft 74. revolubly mounted at its ends in the bearing supports 57 and a threaded follower 75 on the standard 47 of the carriage in mesh with said threaded shaft. A crank handle 76 on said shaft provides means for turning the same whereby said carriage may be shifted from one side of the car frame to the other.

Our machine is propelled in either direction and at variable speeds by the engine 60. A driving clutch member 77, operated by the hand lever 78, coperates with a driven clutch member 79 on the power shaft 5S). Said clutch member 79 is supplied with a restava sprocket wheel 80, and a sprocket chain 81,

machine is employed merely to raise a track,

the thrust boom 43 remains in upright position, and to assist in holding it in such position, we provide a rigid connection between the pedestal and boom to prevent any tendency of the latter to tilt. For this purpose, brace rods 88 are hinged at one end upon pivots 89 on opposite sides of the boom 43 and are formed at the other end with eyes 90 thereon adapted' to be detachably connected by means of pins 91 with eyes 92 on said pedestal, or with eyes 93 on said boom. When the former connection is made, the pedestal is rigidly secured by said rods to the boom and when the latter connection is made, said boom is free to swing and the rods are held in safe inoperative positions.

In use, the machine is placed upon a track to be moved and is propelled to the desired point; it being understood that the base ot' the boom with its pedestal 83 are elevated so as to clear the ground. The lever 19 is thrown to carry the hooks 23 against the webs of the rails when the lever 18 is manipulated to draw'said hooks against the lower sides of the rail heads, thereby firmly clamping the car upon the rails. 1f the purpose is merely to raise the rails to correct theV grade, the. carriage B is moved to the center of the car by turning the crank handle 76. The brace rods 88 are secured to the pedestal 83 on the thrust boom (Fig. 7) and the boom is swung to upright position by manipulating the handle= 73. The clutch members 64 and 65 are then engaged by the manipulation of the hand lever 66, thus connecting the power shaft 59 with the thrust boom 43 through the chain 61,. shaft 56, worm gear 55, worm wheel 53, shaft 49 and spur gear 51, whereupon the pedestal of said boom is thrust against the roadbed (between the ties) and the machine and track are lifted. '1t will be noted that the intermeshin worm wheel 53 and gear 55 provide an efhgcient lock which prevents the car from falling when the clutch members 64 and 65 are disengaged to discontinue the lifting of the car. To raise the thrust boom, the rotation of the power shaft 59 is iirst reversed b throwin the levers 67 and 68, when the clyutch mem ers '64 and 65 are reengaged to again connect said boom with said power shaft.

When it is desired to throw tho track sidewise, the brace rods 88 are disconnected from the pedestal 83 and secured in the eyes 93 on the boom. llhe carriage lB is shifted to one side of the car, in the direction in which the track is to be thrown, and the boom 43 is operatively connected with the engine and thereby lowered, while it is swung to an inclined position by turning the handle 73 so that the descending pedestal '83 impinges againstJ the roadbed, substantially midway between the rails. The car and track at-4 tached thereto are thereupon shifted sidewise.

llt will be seen that by successive operations of our machine as above described, long stretches of track, including both rails and ties, may be readily raised and thrown sidewise as desired.
